walleye-
surely there's at the least an IPSC guy at the range who can let you peek thru on of his spaceguns or raceguns. That was my first experience, a true gentleman at the range I attended allowed me to shoot his comp gun at some falling plates. That was literally 10yrs ago or longer. I remember how easy it was to track plate to plate and just sorta run on auto pilot. That stayed w/ me until I began to see some people taking the dot into LEO, .mil, and finally into cc worlds. And now, well, here I am.
Give any of these folks a call/email and get the first hand scoop on dots:
